PROFILE
Shixuanzhang
Contributed to the E3SM-Project/E3SM repository by developing a dynamic freshwater flux and precipitation scaling framework to improve ocean surface water balance in climate simulations. This work involved implementing daily and yearly scaling logic, integrating scaling factors into restart workflows, and introducing a new namelist section for flexible configuration. Addressed critical bugs related to scaling factor retrieval and initialization, and refactored code for maintainability and alignment with MPAS-O standards. Enhanced configuration clarity by updating parameter descriptions and documentation, reducing onboarding time and misconfiguration risk. Utilized Fortran, Python, and XML, applying skills in scientific computing, configuration management, and numerical simulation.

May 1, 2025May 2025 performance highlights for E3SM development: Delivered a dynamic freshwater flux and precipitation scaling framework to preserve ocean surface water balance in the E3SM ocean component. Key enhancements include a new forcing namelist section, daily/yearly scaling logic, and integration of scaling factors into restarts to ensure conservation across simulations. Implemented extensive bug fixes for SFWF scaling factor retrieval, initialization when balance type is enabled, and restart behavior. Performed targeted code cleanup and refactoring of the scaling framework and related constants to improve maintainability and MPAS-O alignment. Result: improved ocean water balance accuracy, more robust restarts, and a maintainable codebase for future enhancements.
